haha, yeah, i didn't mean to sound like a jerk but reading my post I think that's how I came off. And I was jk about roids. I would SERIOUSLY recommend taking some sort of protein/calorie supplement if you are skinny. Something w/ tons of calories and tons of protein. Cell tech used to work well for me when I was a HS athlete.
But yeah, just get out on the track and ride, man! ride a ton and eat even more! Atlanta is hilly, so you should get out on the roads and do long rides. Do lots of sprints.
